SEBA/ProTorque ™ Brochure - Orthodontist Los Alamitos CA

Orthodontists today use pre-
adjusted appliances that are de-
rived from Caucasian norms. When
treating Asian patients with straight
wire appliances, the clinician must
increase the torque values for both
the upper and lower incisors and
decrease the angulation values in
order to achieve an optimal
interincisal angle and functional
occlusion for Asians. The SEBA
system offers a more natural
position of the anterior teeth to
bone and to each other, which
affects the facial profile and most
importantly, the stability of the
finished orthodontic case.
The relationship between the nose, lips, and chin is one of the most
important considerations in diagnosis and treatment planning. Moving
the anterior teeth in any direction will affect the position of the lips and
overall facial balance.
Evidence-Based Orthodontics
Dr. Raymond Sugiyama has researched the differences between various ethnic groups for the
past ten years. His findings, based on scientific evidence, show statistically significant differences
in the dental anatomy and cephalometric measurements between Caucasians and Asians. Asian
teeth are wider mesio-distally 1 and have less angulation 2,3 than Caucasian teeth. The upper and
lower incisors of Asian teeth are more proclined, in relation to basal bone, than Caucasian teeth,
which results in an interincisal angle that is significantly less. These evidence-based findings have
led to the development of the SEBA prescription. Higher torque and lower angulation of the SEBA
prescription keep the teeth in the middle of the basal bone during orthodontic movement, thereby
lessening the chance for root resorption.
CONCLUSIONS
Comparative differences: Asians and Caucasians based on scientific studies:
1. Upper and lower anterior teeth (related to basal bone) are
significantly more labial inclined
2. The Interincisal Angle is significantly less
3. All teeth are wider except canines 1
4. Asian teeth have less angulation 2

People of various ethnicity show differences in hair, skin and eye color as well as other physical and structural anatomy. The
orthodontist must recognize and respect these differences by placing the teeth in their natural position related to basal bone and
to each other. The SEBA prescription offers patients the advantages of an appliance that will maximize their dental and facial
aesthetics and enhance their chances for long term stability by placing teeth in a more natural and functional position than
Caucasian based straight wire systems.
SEBA is available in Mini Master Series and Virage
metal inserted ceramic brackets.

Orthodontists today use preadjusted
appliances that are derived
from Caucasian norms. When
treating Latin-Hispanic patients with
straight wire appliances, the clinician
must increase the torque values
for both the upper and lower incisors
and decrease the angulation
values in order to achieve an optimal
interincisal angle and functional
occlusion. The ProTorque system
offers a more natural
position of the anterior teeth to
bone and to each other, which
affects the facial profile and most
importantly, the stability of the finished
orthodontic case.
The relationship between the nose, lips, and chin is one of the most
important considerations in diagnosis and treatment planning. Moving
the anterior teeth in any direction will affect the position of the lips and
overall facial balance.
Evidence-Based Orthodontics
Dr. Raymond Sugiyama and Dr. Mauricio Gonzalez Balut have conducted
extensive research into the rationale for a bracket prescription
different from standard prescriptions which are derived from
measurements of Caucasians. Evidence-based data shows statistically
significant differences in the dental anatomy and cephalometric
measurements when comparing Caucasians to other ethnic patients.
For example, studies show that the interincisal angle of Asian, Black,
and Latin-Hispanic patients ranges from 10 - 16.6 degrees less
when compared to Caucasians 1,5 . This is the result of the increased
proclination of the upper and lower incisors relative to basal bones
in these groups. This fact suggests the need for more torque in the
anterior teeth for this group of patients.
All teeth of Asians and Latin-Hispanics are wider mesio-distally than Caucasians’ teeth 3 . Wider teeth need less angulation. This
fact is shown in studies by Motegi in Japan 4 . The ProTorque prescription is ideally suited for Asian, Black, and Latin-Hispanic
patients and also patients with Division 2 type malocclusions. The added torque keeps the roots in the middle of the basal
bone and helps to maintain the natural fullness of the lips in this group of patients.
